Congrats! I just got mine about 6 days ago. I love it.

What did you have before? And what PP program do you use?

I upgraded from crop body, and am enjoying the low-light ability. Amazing to shoot 3200 with better IQ than I used to get at 1600 or 800. As for PP, I was a little shocked to realize I had to upgrade from LR3 to LR4 (to let Adobe read the 6D's Camera RAW), but having jusdt done so, I really like the new version.
